I have the following data sets:
A list of users.
Tom, Lisa, Karen
These users can manage any shop (one or more):
Barba, Rentraum, Kisabran, Tespot and Lowvel
These shops can provide any services/products:
Yoga, Coffee, Mechanics, Gym
These services can receive a complaint, which can only BE for ONE service at a given SHOP!
Complaint 1 -> Yoga at Kisa Complaint 2 -> Yoga at Tesport Complaint 2 -> Cofee at Barba etc
Now, I want at any time to PASS the user_id (Tom, Lisa, Karen) to a query, and get all COMPLAINTS eligible to that user.
